    作为一个开发者tortoisegit/tortoisesvn当然时少不了的； 最近发现tortoisegit/tortoisesvn不在显示了，文件修改后也不变红； 刚开始以为是被360有优化掉了；查看了一下启动项和进程；没问题 TSVNCache.exe进程就是负责决定在tortoise管理下的每个文件、文件夹应该显示哪个图标； 公司电脑和我自己的电脑都有这个问题； 搜索引擎上找了一下： 找到了结论 Windows Explorer Shell 支持的 Overlay Icon 最多 15 个，Windows 自身使用了 4 个，只剩 11 个可扩展使用。 360cloud（云盘）、百度云盘、OneDrive、skyDrive等软件都会占用；而每个软件都会尽量让自己的优先生效； 我最近装了微软的OneDrive所以就出问题了； 解决办法： 修改 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellIconOverlayIdentifiers 里注册的优先顺序；使得Tortoise尽量靠前；顺序是按照ascii码的顺序来的； 盗一个图 注意：有些软件再你修改后，下次启动时会再次修改顺序；你要想办法解决这个问题！ &nbsp; &nbsp; 详细可以参考： http://blog.csdn.net/chaoyuan899/article/details/9128939 http://www.oschina.net/question/2297147_245156

    利用virt-what工具检测VPS虚拟化技术 检测是OpenVZ还是Xen老蒋 发布于 1年前 (2014-09-26) 分类：VPS基础应用阅读(543) 评论(0) 我们在选择VPS主机的时候肯定会看到商家提供方案有提到是用的openvz、xen、kvm等架构技术，具体我们不去讨论这3个常用的技术特点，总之相对而言，openvz可以超售比较多，所以相对成本就低，对于xen和kvm理论上操作可以超售部分，但相对比ovz好一些。 对于我们购买的VPS，也可能听到的技术不准确，可以用到virt-what方法来真实的检测。 第一、下载以及安装virt-what脚本 wget http://soft.itbulu.com/tools/virt-what-1.11.tar.gz #下载 tar zxf virt-what-1.11.tar.gz #解压 cd virt-what-1.11 #进入目录 ./configure #设置 make && make install #编译安装 理论上是可以操作没有问题的，但是在执行make && make install的时候会出现&#8221;make: *** No targets specified and no makefile found&#8221;的错误提示。 解决方法： yum install gcc gcc-c++ autoconf automake 安装必备的组件支持。 然后我们在操作： ./configure make && make install 这样就可以把virt-what安装成功。 第二、检测系统架构技术 virt-what 可以检测到老蒋这台机器使用的openvz，与官方卖给我的是一样的，没有骗我。 转载from: http://www.itbulu.com/virt-what.html

    阀值是阈值的常见错误写法。 引用同事说的一句话&#8221;阀值是阈值的文盲写法&#8220; 阀fá 控制、开关、把持。1) 机械名词,指在管道中用来控制液体或气体的部件。意为阀门、开关、把持。如截止阀、减压阀、安全阀。 阈(yù )范围,边界,程度。1) 门槛、门限,引申为边界、界阈、视阈。 可见“阀”与“阈”是词义不同的2个词。那么“阀值”会不会是一个新词呢? 经查，不是。在表达“界限”、“范围”的意思时应该用“阈”而不是“阀”。阈值跟英文threshold value对应。 在新版的《现代汉语词典》和《现代汉语规范词典》中，均没有收录“阀值”一词 ；但在日常生活、甚至许多科研论文中，都普遍存在误用的现象。 from 百度百科 http://baike.baidu.com/subview/648990/648990.htm
